How it works

Fahrenheit and Celsius don't share a zero, so it isn't a single multiply: °F = °C × 9/5 + 32, and °C = (°F − 32) × 5/9. Kelvin is Celsius shifted by 273.15, so 0 K is absolute zero.

Worked example

0 celsius is 32 °F.

Questions

What is 180°C in Fahrenheit for an oven?

356°F, usually rounded to 350°F on oven dials. For a fan oven, recipes often suggest about 20°C lower.

Is there a quick way to estimate °C to °F?

Double it and add 30. It's close for everyday temperatures: 20°C → about 70°F (exactly 68°F).

At what temperature are Celsius and Fahrenheit the same?

−40. That's the only point where both scales give the same number.
